Emission Spectra Quick Check
1. What do the characteristics of electromagnetic radiation include?
characteristics of both waves and particles
2. Which equation correctly relates the energy of electromagnetic radiation to its frequency?
E=hv
3. What causes electrons in atoms to emit energy after absorbing it?
returning to their ground energy states
4. What observation led scientists to postulate the existence of photons?
electrons in atoms emitting energy only in certain amounts
5. How are the wavelengths of the emission spectra of an element related to its electron configuration?
The wavelengths of the emission spectra of an element are related to its electron configuration because each element has a unique electron configuration, which determines the energy levels and transitions that can occur in its atoms, resulting in a unique set of wavelengths in its emission spectra.
